IMPROVEMENT IN PRlNTlNG-PRESSES.

Specification forming part of Letters Patent No. 162,650, dated April 27, 1875; application filed October 13, 1873.

To all whom it may concern:

Be it known that I, JAMES HINOHCLIFF, of Bromley, in the county of Middlescx, England, subject of the Queen of Great Britain, have invented certain Improvements in Printing-Presses, which said improvements were patented in England on the 5th day of June, 1872, and numbered 1,705, of which the following is a specification:

My invention relates to printing presses, and more particularly to those known as per fleeting-presses; and consists, first, in a novel construction, combination, and arrangement of mechanism for drying the ink upon the sheets as they pass through the printingmachine, and thus facilitate the operation of printing perfected sheets and the second partof my invention consists in a novel combination and arrangement of mechanism for shuting off the gas-flame simultaneously with the stoppage of the press.

Figure I is a side elevation of a perfecting machine with my improvements. Fig. 2 is an end view of the same. Fig. 3 is a sectional detail.

In the drawing, A A show the side frames of a printing-press secured to the bed B; G, the driving-pulley, and C a loose pulley. D shows a gas-tube, which rises from the bed B about half the vertical distance of the frame A. On the upper part of pipe D a branch pipe, E, is screwed, the ends of which enter the tubes F F, located transversely of the machine. In'a series of bosses on the upper sides of the pipes are screwed the tubes G G, which enter the larger slitted gas-tubes H H, extendin g downward from the under side of the tubes I I, situated under and parallel with the first impression cylinder. This arrangement is shown in detail at Fig. 3, the space between the tubes G and H afi'ording a passage for air, which mingles with the gas from the tube G before it issues from the longitudinal slit a in the pipe I, and when lit forms a long narrow sheet of flame along the tube. The flametubes I I are situated below, on each side of the first impression-cylinder, and as the paper passes between this cylinder and the first typecylinder it is carried along on the impressioncylinder with its freshly-printed side presented to the flames, and'oiiTtrfii ing at" thsecond impression-cylinder the ink is sufficiently dried to prevent its setting off on the blanket of the second impression-cylinder,/

It will be necessary on stopping the machine to shut 05 the gas, and to do this the supplypipe D is provided with a stop cock, J, the crankhandle b of which is operated by the pitman (J, connected with the slide-bar d, to which is secured the belt-shipper c, which runs the belt on and ofi' the driving-pulley U, and it will be readily seen that as the bar d is reciprocated the stopcock will be opened and closed.

To protect the first type-cylinder from the effects of the heat, a sheet-metal plate may be introduced between it and the flame.

I claiml. The combination, with two or more type and impression cylinders, whereby a web is printed on opposite sides, of a series of gasburners, which direct heat upon said web at a point between the first type and first impression cylinders, or between the first and second. impression-cylinders, whereby the ink is dried to prevent its ofisetting, substantially as described.

2. In a printing-press having impression and type cylinders, the combination of the slitted gas-tubes I I with the shipper c, cock J in pipe D, and connecting-rod c d for shutting off the gas supply simultaneously with the stopping of the press, substantially as described.

JAMES HINOHGLIFF.
